Claims This invention relates to installations for controlling sluice valves. t

It is becoming more and more usual to control sluice valves mechanically by installing next to them control tricky and sometimes expensive work.

Then again special valves have been proposed which themselves provide the seatings for the installation of control members. This type of special construction is obviously particularly costly and is only suitable when installing new valves.

bands to any existing part of a valve.

In a practical embodiment of the invention the gripping bands lixing the carrying shaft are arranged on the anges of the valve.

`to move thereon.

To make the In the drawing 1 is a sluice valve already installed, which is to be controlled by a control device such as a servo motor 2, for example.

The fixing means according to the invention, adapted to support the control device 2, consists of a carrying shaft 3 clamped between two half-collars fixed to and capable of moving on a shaft 5 carried by cheeks 6.

A gripping band 7 is partly Wound round the shaft 5 and engages in a slot 8 provided on a tightening pin 9 65 part on the valve, in this case a liange 11.

The same device is provided for the other flange (not visible) of the body 12 of the valve.

rying shaft 3 and the shaft of the valve.

A metallic band 21 similar to the band 7 is arranged around the liange 22 of the Valve. It is partly wound round the spindle 18, passes round a pin 25 with square head 26.

To keep the bands 7 and 21 tight, screw fixing clamps 27 are provided iii the cheeks 6.

The spindle 23 also receives a rod 28 which may be opening in a collar-plate 30 which collar-plate.

Under these conditions it any mechanical control device may be installed without belts, chain, etc.

I claim:
